In London, who are the people protesting against President Trump?

I am just unsure how it could be deemed relevant in the event of certain crimes. Relevance is key here.

If you were a burglar for example it matters not a jot if you are English, Irish or Arab.

But if law-enforcement authorities use the data to identify that 90% of burglaries are committed by Irish, for example, they might be able to address the issues within the Irish community which lead to them being drunken, belligerent, sectarian, wife-beating thieves.
